Overview
CT scan findings associated with chronic cholecystitis include gallbladder wall thickening, gallbladder distension or contraction and subserosal edema.
CT scan
- CT scan is more specific than ultrasound. CT scan findings include:[1][2][3][4]
- Gallbladder wall thickening
- Gallbladder distension or contraction
- Subserosal edema
- High attenuation gallbladder bile
- CT cannot identify noncalcified gallbladder calculi and cannot assess for Murphy's sign.[5][6]
Acalculous Cholecystitis
The CT based diagnostic criteria from multiple studies for acalculous cholecystits is as follows:[7]
| Criteria | Diagnosis |
|---|---|
| Major | 3 to 4 mm wall thickness Pericholecystic fluid Subserosal edema Intramural gas Sloughed mucosa |
| Minor | Hyperdense bile (sludge) Subjective distension (hydrops) |
Diagnosis: The diagnosis requires 2 major or 1 major and 2 minor to be positive.
